Pain Points in the Protein Industry

Like every other industry, despite quick growth, there are several core challenges that need to be addressed: 

1. Low Functional Properties

• Issues: Bad solubility, gelation, foaming, emulsification,
  
• Root Causes: Aggregation, polyphenol interaction, pH sensitivity
  
• Impact: Limited application across food formats (e.g., beverages, bakery)
  

2. Unsustainable Ingredients & Extraction Methods

• Issues: Chemical-heavy processes, high carbon footprint, low yields
  
• Root Causes: Solvent use, unsustainable crop sourcing (e.g., soy), energy-intensive wet methods
  

3. Identifying the Right Protein Source

• Issues: Lack of cross-functional usability, incomplete amino acid profiles
  
• Root Causes: Varying requirements across applications (texture, stability, mouthfeel)
  

4. Undesirable Off-Flavors

• Issues: Beany, bitter, or metallic aftertastes in plant proteins (pea, fava)
  
• Root Causes: Volatile compounds (e.g., hexanal), chemical residues, saponins
  

Innovative Solutions: Moving the Industry Forward

1. Improving Functional Properties

• Companies like FlavaPulse and Ingredion are customising proteins for specific applications such as beverages and bakery products
  
• Advanced extraction methods—enzyme-assisted, ultrasonic, microwave-assisted, and deep eutectic solvents (DES)—are improving solubility, emulsification, and gelling properties
  

2. Off-Flavor Elimination

• Steam/wet-heat treatments and dual-stage dehulling are mitigating undesirable notes
  
• Fermentation and enzyme treatments are being used alongside flavor masking agents to enhance palatability in meat and dairy alternatives
